GAS BURNER.

Application led .Tuly 12, 1927. Serial No. 205,227.

This invention provides a burner which is self cleaning and not liable to become choked, or have its efhciency impaired by particles dropping therein from above.

The invention furthermore provides a burner which assures a thorough mixing of air and gas and which practically offers no impediment to the free liow of heat.

NVhile the drawing illustratesa preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding` of the invention and the merits thereof, reference is to be had to the following description and the drawing hereto attached, in which* Figure l is a front view of an embodiment of the invention, parts being in section.

Figure 2 is a horizontal section of a burner on the line 2 2 of Figure l.

. Corresponding and like parts are referred to in the following description and designated in the views of the drawing by like reference characters.

The numeral l designates the body of a heater and associated therewith is a gas pipe 2 provided in its top side with gas outlets 3. The numeral 4; designates a burner support which is located a distance above the pipe 2. Openings 5 are formed in the support 4 in line with the outlet 3 and the burners are fitted thereto.

In the preferred form of burner the same comprises a mixing tube 6 and burner tube 7, the latter being disposed at the side of the mixing tube and spaced therefrom. The upper end of the mixing tube 6 is connected to the burner tube 7 at a point intermediate the ends thereof. The connection between the mixing tube 6 and the burner tube 7 flares outwardly, the top wall 8 inclining upwardly from the mixing tube and the bottom wall 9 inclining downwardly from the mixing tube. Any particle or substance dropping into the burner tube will ass therethrough, and not tend to lodge therein, and should it strike the wall 9 it will be deflected so as to continue downwardly through the tube. The upwardly inclined wall 8 offers a minimum resistance to the flow of the 56 gaseous mixture from the tube 6 into the tube 7. I'Vhen the burner embodies two burner tubes, as shown in the accompanying drawings, said tubes are oppositely disposed a like distance from the mixing tubes, and 60 the top walls of the connection are oppositely disposed, and are arranged to deflect the gaseous mixture equally to each of the burner tubes. The lower end of the mixing tube may pass through the opening of the support 4 and held in place by an outer flange l0, or it may enga-ge over a collar l1 in line with the opening 5.

In practice, gas being supplied to the pipe 2, escapes therefrom in a jet through the outlet 3, and entering the tube 6 draws air into said tube from the space therebelow. The air and gas mix in the tube 6 and pass therefrom into the burner tube 7, and upwardly through the latter. This results in creating a draft through the burner Atube and drawing additional air therein, which mixes with the gas entering the upper portion of the tube, whereby an intense flame is produced when the gas is ignited at the upper end of the burner tube.

aving thus described the invention, we claim:

l. A gas burner comprising a mixing tube, and a burner tube at the side of the mixing tube and open throughout its length and connected intermediate its ends with the mixing tube, the connection having its top and bottom walls oppositely inclined from the mixing tube.

2. A gas burner comprising a gas supplying pipe having an outlet, a mixing tube supported above the out-let in line therewith, and burner tubes at the sides of the mixing tube and connected intermediate their ends to the top of the mixing' tube, the connection flaring outwardly from the mixing tube to provide top and bottom walls which are oppositely inclined.

In testimony whereof we aix our signatures.

WILSON NEWMAN.
